This cleans up the /proc/device-tree representation of the Open Firmware
device-tree on ppc and ppc64. It does the following things:
- Workaround an issue in some Apple device-trees where a property may
exist with the same name as a child node of the parent. We now
simply "drop" the property instead of creating duplicate entries in
/proc with random result...
- Do not try to chop off the "@0" at the end of a node name whose unit
address is 0. This is not useful, inconsistent, and the code was
buggy and didn't always work anyway.
- Do not create symlinks for the short name and unit address parts of a
node. These were never really used, bloated the memory footprint of
the device-tree with useless struct proc_dir_entry and their matching
dentry and inode cache bloat.
This results in smaller code, smaller memory footprint, and a more
accurate view of the tree presented to userland.

This is the ppc32 patch equivalent to the just posted ppc64 one working

Apple's Open Firmware has a funny bug when creating the /cpus nodes
where it leaves a dangling '\0' character in the CPU name which ends up
appearing in the full path of the node. This is bogus and
confuses /proc/device-tree badly.
This patch strips those bogus zero's from the node full path when
reading the device-tree from Open Firmware. The "name" property is not
modified and still contains the spurrious 0 (it basically contains 0
tailing 0 instead of one) but that shouldn't be a problem.
An equivalent patch for ppc32 will follow shortly

With the release of the dual-core AMD Opterons last week,
it's high time that cpufreq supported them. The attached
patch applies cleanly to 2.6.12-rc3 and updates powernow-k8

Update the driver to version 1.40.0 and provide support

We have to recalibrate cpu_khz in order to use the current FID instead the max
FID since some BIOS do not put the processor at maximum frequency at POST.
Also, some BIOS will change the processor frequency at our back after cpu_khz
was calibrate. Finally, this will fix a long standing bug when we do
something like this:
# rmmod powernow-k7
# modprobe powernow-k7

Patch from Charles Spirakis
Some linux customers want to optimize their applications on the latest
hardware but are not yet willing to upgrade to the latest kernel. This
patch provides a way to plug in an alternate, basic, and GPL'ed PMU
subsystem to help with their monitoring needs or for specialty work. It
can also be used in case of serious unexpected bugs in perfmon. Mutual
exclusion between the two subsystems is guaranteed, hence no conflict
can arise from both subsystem being present.

acpi_request_vector() is called in ia64_mca_init() to get the cpe_vector.
The problem is that acpi_request_vector() looks in platform_intr_list[] to
get the vector, but platform_intr_list[] is not initialized with a valid
vector until later (in sn_setup()). Without a valid vector the code
defaults to polling mode.
This patch moves the call to acpi_request_vector() from ia64_mca_init()
to ia64_mca_late_init(), which is after platform_intr_list[] is initialized.

Some time ago, GAS was fixed to bring the .spillpsp directive in line
with the Intel assembler manual (there was some disagreement as to
whether or not there is a built-in 16-byte offset). Unfortunately,
there are two places in the kernel where this directive is used in
handwritten assembly files and those of course relied on the "buggy"
behavior. As a result, when using a "fixed" assembler, the kernel
picks up the UNaT bits from the wrong place (off by 16) and randomly
sets NaT bits on the scratch registers. This can be noticed easily by
looking at a coredump and finding various scratch registers with
unexpected NaT values. The patch below fixes this by using the
.spillsp directive instead, which works correctly no matter what
assembler is in use.

I noticed this typo when trying to compile a kernel which had
CONFIG_HOTPLUG turned off. In that case, __devinit is no longer a
no-op and the compiler then detects a section-conflict. Fix by using
__devinitdata instead of __devinit.

using sim_defconfig (which has CONFIG_HOTPLUG=n).

The error checking for emulation of load string instructions was overly
generous and would cause certain valid forms of the instructions to be
treated as illegal. We drop the range checking since the architecture
allows this to be boundedly undefined. Tests on CPUs that support these
instructions appear not do cause illegal instruction traps on range errors
and just allow the execution to occur.
Thanks to Kim Phillips for debugging this and figuring out what real HW was
doing.

jail mode has been dropped, together with that use, so let's finish dropping
